Weather in September
Temperature
September heralds a minor drop in average high-temperature, sliding from August's 94.3°F (34.6°C) to a still hot 87.8°F (31°C). Throughout September, the nighttime temperature averages to an enjoyable 67.1°F (19.5°C).Heat index
The heat index in September is evaluated at a torrid 98.6°F (37°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
